4. Running a project:

• Open the project in MPLAB X IDE
• Open main.c file inside source
• Click on the build icon on the top
• A .hex file is generated inside Project Folder > dist > default > production > filename.hex
• Open the Simulation file (with a .pdsprj extension) in Proteus
• Double Click on the mcu to bring out the configuration menu
• Browse and select the .hex file and click Ok
• Click on the run button at the bottom to simulate

5. PIC16F877A Pinout Diagram

PIC16F877a is a powerful (200 nanosecond instruction execution) yet easy-to-program (only 35 single word instructions) CMOS FLASH-based 8-bit microcontroller packs Microchip's powerful PIC® architecture into an 40- or 44-pin package and is upwards compatible with the PIC16C5X, PIC12CXXX and PIC16C7X devices. The PIC16F877A features 256 bytes of EEPROM data memory, self programming, an ICD, 2 Comparators, 8 channels of 10-bit Analog-to-Digital (A/D) converter, 2 capture/compare/PWM functions, the synchronous serial port, Asynchronous Receiver Transmitter (USART). All of these features make it ideal for more advanced level A/D applications in automotive, industrial, appliances and consumer applications.
